TABLE-LAMP ATTACHMENT.

Specification of Letters Patent.

Patented Nov. 7, 1916.

Application filed February 9, 1916. Serial No. 77,160.

To all whom it may concern:

Be it known that I, JAMES S. Cmrrono, a citizen of the United States,and a resident of Weehawken, in the county of Hudson and State of NewJersey, have invented a new and Improved Table-Lamp Attachment, of whichthe following is a full, clear, and exact description.

This invention relates to a table lamp attachment whereby the lamp canbe applied to a vase which forms the base or support for the lamp.

The invention has for its general objects to provide an attachment ofthis character which is comparatively simple and inexpensive tomanufacture, reliable and efiicient in use, andso designed as to beadaptable to vases having necks of difi'erent sizes.

A more specific object of the invention is the provision of a pluralityof spring gripping members which are adjustably fastened under thebottom or base of the lamp and are adapted to extend into the neck ofthe vase to thereby tightly hold the lamp attached to the same, thewhole attachment being of such a nature that it can be applied to tablelamps of ordinary construction.

With such objects in view, and others which will appear as thedescription proceeds, the invention comprises various novel features ofconstruction and arrangement of parts which will be set forth withparticularity in the following description and claims appended hereto.

In the accompanying drawing, which illustrates one embodiment of theinvention and wherein similar characters of reaerence indicatecorresponding parts in both the views, Figure 1 is a sectional view of atable lamp with the attachment applied thereto and holding the lampattached to the neck of a vase; and Fig. 2 is a view of the bottom ofthe table lamp with the attachment applied thereto.

Referring to the drawing, the table lamp A is applied to and held inplace on a neck 1 of a vase or similar receptacle B by means of theattachment 0 which is fastened to the base of the lamp. The lamp, whichis of the usual construction, comprises a hollow or chambered base 2, astem or pipe 3, a head 4 on the upper end of the stem, sockets 5 carriedby the head, lamp 6 in the socket, and a suitable shade 7, the electriclamps being supplied with current through circuit wires 8 which passupwardly through, the base 2, stem 3, head 4: to the sockets 5.

The attachment C embodies a plurality of spring gripping or holdingdevices 9 which have vertically disposed resilient .60 members 10 andhorizontal attaching members 11, so that each device 9 is of L-shapedform. The upper members 11 are radially' disposed and they overlap attheir inner ends, each having a longitudinal slot 12, sothat when themembers 9 are in proper posi-- tion the slots will transecteach other toreceive a clamping screw 13 at the point of intersection, the screw 13screwing into a hickey 14. The outer portions of the members 11 arebraced by passing through guides formed by oppositely disposed lugs 15on the periphery of an annular bracket member 16, such member having anupwardly-extending hollow boss 17 to form a chamber in which the hickey14 is disposed. The guide lugs 15 provide for a sliding connectionbetween the members 9 and the bracket member 16, so that the members 9can be moved inwardly or outwardly to adapt the attachment to vaseshaving necks of different diameters. The boss 17 has an inwardlyextending flange 18 which engages under the central portion of the base2 and over the hickey 14, which latter has a threaded nipple portion 19which screws into the stem 3. Thus, by screwing the hickey in place theparts 2, 3 and 16 are clamped together. The hickey has openings atopposite sides for admitting the wires 8. The gripping devices 9 areclamped in adjusted position by the head of the screw 13 engaging thelowermost member 11 and the uppermost member engaging the bottom of thehickey.

Having thus described my invention, I claim as newand. desire to secureby Letters Patent:

1. The combination of a lamp base, a stem fastened thereto, a hickeyhaving 100 threaded connection with the stem, a bracket disposed underthe base and clamped between the latter and hickey, attaching membersadjustably mounted on the bracket, and a fastener clamping the membersto the 105 hickey in different positions of adjustment.

2. The combination of a lamp base, a hickey, a bracket having a hollowboss in which the hickey is disposed, the boss being provided with aninternal flange clamped 110 between the hickey and base, L-shapedattaching members guided on the bracket, and a fastener common to allthe members and clamping the same to the hiekey.

3. The combination of a lamp base, a hickey, a bracket having a hollowboss in which the hickey is disposed, the boss being provided with aninternal flange clamped between the hickey and base, L-shaped attachingmembers guided on the bracket, said members having overlapping slottedportions with their slots intersecting, and a fastener passing throughthe slots and connected with the hickey for clamping the members indifferent positions of adjustment.

4. The combination of a table lamp base, an annular bracket disposed inthe base and having at its periphery radially disposed guides, a hickeyfor clamping the bracket to the base, L-shaped attaching members havinghorizontal slotted portions movable in the guides, the slots of themembers intersecting at a point under the said hickey, and a screwextending through the slots in the members and screwing into the saidhickey for clamping the members in difierent positions of adjustment.

In testimony whereof I have signed my name tb specification in thepresence of" two subscribing witnesses.
